Question

If angle 0 (with a line through it) is an angle in standard position whose terminal side passes through the point (5,12) then sin20 (the zero also has a line through it here) =

12/13
119/169
120/169
24/13

Answer 1

Can I get the answer then an explanation thank you.

Answer 2

Now calculate angle theta. Use the inverse Tan function.
Step 2. Multiply the angle found above by 2.
Step 3. Use calculator and find sine of angle found in step 2.
